Myler Stainless Steel Dee without Hooks, MB 33 Medium Wide Ported Barrel, Level 3 The MB 33 is the mildest Myler mouthpiece in terms of tongue pressure. The generously wide port allows room for the tongue to pass almost completely under the bit. Because this mouthpiece does not rotate on to the tongue and the port is wide, it applies little to no tongue pressure, working primarily off the lips and bars. The port on this mouthpiece is only 1 ½" high, so it will apply little to no palate pressure. Because the MB 33 offers such a high degree of tongue relief, the horse that goes well in this mouthpiece has a trustworthy and consistent disposition, and is trained to work off the leg and seat as well as the hands. Independent Side Movement Stainless Steel Mouthpiece Curved Mouthpiece Copper Inlay NOT Dressage Legal - See MB 33WL mouthpiece. Notes: For a slight increase in tongue pressure, see the MB 43LP or MB 43MP. For same tongue relief without Independent Side Movement, see the MB 16 (Western only). For the same tongue relief and Independent Side Movement, but with a slight degree of collapse, see the MB 05. For more generous tongue relief, see the MB 16PB. The dee without hooks is a traditional "D" shaped cheek with fixed attachment of the mouthpiece. This style keeps the mouthpiece from draping on the tongue, providing a more direct signal than the loose ring. The straight side of the dee will not pull through the mouth and does not pinch. Size: 3 ¾" dee ring on 5" mouthpiece, 3" pony dee ring on 4 ½" mouthpiece Action: Direct Notes: For a more versatile version of the cheek piece, see the English dee with hooks or the eggbutt with hooks.
